.WELL-DRILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 781,234, dated January31, 1905.

Application filed December 15, 1903. Serial No. 185,212.

']'0 all whom it 777,012.] concern.-

Be. it known that I, LEONARD D. SHRYocK, a citizen of the United States,residing at Marietta, in the county of Washington and State of Ohio,have invented certain new and useful Improvements in Well-DrillingMachines, of which the following is a specification, reference being hadthereinito the accompanying drawings. s

This invention relates to a portable machine for drilling oil, gas, andother deep wells; and the primary object is to provide effectivemechanism of simple'and improved construction foractuating thedrilling-cable when spudding and to so arrange the machine that thespudding mechanism is a permanent part thereof, which may beconveniently connected and disconnected from the driving mechanism.

A further object is to improve and simplify the general construction ofthe machine.

In the accompanying drawings,'Figure 1 is a side elevation of theimproved machine, a portion of the mast or derrick being broken away;and Fig. 2 is a rear end view of the machine-frame, illustrating theposition of the Fig. 3 is a top plan view, partly in section; and Fig. Ais a longitudinal sectional view on line 4 4: of Fig. 3.

Referring to the drawings, 2 and 3 are the longitudinal side members ofthe machineframe, which are connected by cross members 4, the wholebeing mounted on groundwheels 5.

6 is the engine, arranged at the forward end of the machine-frame onadjustable base 7, the adjustment being effected by threaded rods 8,projecting from said base through brackets 9 on the frame, with nuts 8operating in conjunction with the brackets, as shown. The adjustment isfurther maintained by vertical clampingbolts 10, which engage theslotted lower portion 7 of the base. This adjustment of the engineprovides a convenient and ready means for tightening belt 11,.

running from'driving-pulley 12 to band-wheel 13, the latter beingcarried by shaft 14, journaled transverse the rear portion of the frameand provided at its opposite end with crank 15, which serves to operateboth the spudding mechanism and the walking-beam.

16 is the drilling-cable reel, mounted within the frame on transverseshaft 17, the latter carrying wheel 18, upon which operates handbrake19,operated by lever 20, whereby the reel is controlled in paying out thedrillingcable 21. a shaft 22 is provided carrying pinion 23, whichmeshes with gear 23 on reel-shaft 17, the gearing being thrown in andout of rota- For winding or spoolingthe cabletive connection with shaft22 by clutch 24.

The opposite end of shaft 22 is journaled in eccentric bearing 25,operated bylever 26 and rod 26, and on the end of the shaft is withinner periphery 13 of band-wheel 13.

Shaft 30 is so positioned that this frictional engagement is had at apoint rearwardfrom shaft 14:, so that the pull of driving-belt 11 on theband-wheel operates to maintain and render effective said engagement,whereas if the arrangement were such as tocreate a tendency on the partof the band-wheel when under strain to pull away from pulley 33 thefriction-drive-would be far less eflfective.

34 is the pole mast or derrick, positioned at the front of the machineand braced by guys (not shown) and carrying crown-pulley 35, from whichdrilling-cable 21 depends to the drilling-tools 21, the cable passingfrom the reel to a sheave 36, .arranged at any convenient point on thefront portion of the machine,

and from thence to the crown-pulley.

For reciprocating the drilling-cable in the In moving away fromoperation of spudding, as when starting the hole, a spudding-line 37 isconnected to the cable by shoe 38, through which the cable moves freely,said line passing over sheave 39, journaled on shaft 40, the latterbeing at the rear of shaft 14, and from this sheave said line detachablyconnects with wrist 15 of crank 15. Owing to the diagonal pull of line37, sheave 39 is arranged at angle to the plane of the machine-frame,being approximately in the plane of the line of pull. The portion ofline 37 operating over sheave 39 consists, preferably, of a section ofchain 37, which withstands the frictional wear much better than rope.Thus a most simple, direct, and effective operation is provided for thespudding mechanism. As I claim to be the first to provide an angularlyarranged powertransmitting element intermediate the driving-crank andthe drilling cable to compensate for the diagonal pull of thespuddingline I do not confine myself to the embodiment thereof hereindisclosed.

The Samson-post 4:1 is mounted on the machine-frame in the usual mannerfor supporting the walking-beam 42, which operates the cable for thedeeper drilling in manner well understood in the art. The beam-pitman4:3 operatively connects with crank-wrist 15' for such use, thespudding-line having been disconnected therefrom and remaining inactivewhile drilling with the beam.

I do not confine myself to the exact structural features herein shownand described, as the several features of the invention may be variouslyembodied without departing from the spirit and scope thereof as definedby the appended claims.

I claim 1. In a well-drilling machine, the combination of adrilling-cable, an actuating member, and power-transmitting mechanismconnecting the cable and said member and constructed and arranged toexert a pull on the actuating drilling-cable in a plane oblique to theplane of movement of the actuating member.

3. In aspudding attachment for a well-drilling machine, the combinationof an actuating member, a spudding-line connected at one end thereto andadapted to be reciprocatcd thereby, and a sheave over which the linepasses, said sheave intersecting the plane of movement of the actuatingmember and arranged obliquely thereto.

I. In a well-drilling machine, the combination of a frame, a shaftjournaled therein having a crank, a drilling-cable at one side of theplane of movement of the crank, a line connected at one end to the crankand at its opposite end to the drilling-cable, and guiding means forsaid line constructed and arranged to direct the line to the cranksubstantially in the plane of movement thereof.

5. In a spudding attachment for a well-drilling machine, the combinationof an actuatingcrank, a spudding-line connected at one end thereto, anda guiding-sheave for said line rotatable in a plane oblique to the planeof retation of the actuating crank.

6. In a spudding attachment for a well-drilling machine, the combinationof an actuatingcrank, a spudding-line connected at one end thereto, anda guiding-sheave for said line at the rear of the said crank androtatable in a plane oblique to the plane in which the crank rotates.

7. Inadrilling-machine, the combination of a shaft having a crank,adrilling-cable in front of the shaft, a line operatively connecting thecrank and cable, and a guiding-sheave for said line disposed in a planeoblique to said shaft and at the rear thereof.

8. In a well-drilling machine, the combination of a shaft having acrank, a drilling-cable at one side of the plane of movement of thecrank, and power transl'nitting mechanism connecting the cable and saidcrank and constructed and arranged to exert a pull on the crank indirection substantially in the plane of movement of the latter and toexert a pull on the drilling-cable in direction oblique to said plane ofmovement.

In testimony whereof I afiix my signature in presence of two witnesses.
